They use a snorkel device pioneered by the Germans in WWII. This does not change the validity of your answer regarding nuclear subs, though. | |

Simply using conservation of energy, we can show that it is impossible for a diesel sub to generate enough electricity to generate oxygen. If fact, most diesel subs, don't run the engine under water, but use batteries to conserve oxygen. | |

Minisubs, much like SCUBA divers, carry bottled air and presumably also use scrubbers. Aircraft that were genuinely airtight would need to carry a lot more equipment. | |
